The CPU control board monitors the temperature above the cooking area and is equipped with an audible alarm that will sound if the system is activated. It also monitors the battery voltage and will chirp when the battery needs to be replaced.

Electric

The Electric Shutoff Assembly G319-A is the standard shutoff supplied with the G300B system. Features provided with this shutoff include the following:

1. A “Fail Safe Mode” consisting of a Normally Open (N/O) Contactor that is energized continually. Activation due to a fire will open the contactor, disconnecting "electrical power” supply lines to the stove.

3. Two extra set of dry contacts for switching external devices during system activation are provided via opyional Interface Enclosure Assembly.

4. The shutoff also has a latching feature to eliminate any possibility of an automatic reset of the power supply after a fire. To restore power to the stove simply disconnect power to the electric shut off device by flipping its breaker off and then on again.

Gas

The Gas Shutoff Assembly G316-A is the standard shutoff supplied with the G300B system. Features provided with this shutoff include the following:

1. A “Fail Safe Mode” consisting of a Normally Closed (N/C) valve that is energized continually. Loss of power or activation due to a fire will close the valve, shutting off “gas flow” and “electrical power” to the stove.

The Interface Enclosure Assembly provides one set of dry contacts when connected with the Gas Shutoff (P/N G316-A) and two sets of dry contacts when connected to the Electric Shutoff. Contact rating is 120 VAC 5 amps.

The optional Sonic Receiver Assembly will work with either any configuration of Electric Shutoff (P/N G319) or the Gas Shutoff (P/N G316-A). Some site conditions have difficulty installing the standard Interconnect Cable from the Main CPU control board.

For convenience and ease of installation, the Sonic Receiver Assembly provides a remote sonic activation.
